The Hawaii State Archives has a card list for deceased veterans of the Spanish-American War, Civil War, and World War I. Also in its collection is a list of Hawaiians who served in World War I and members of the Guard of the Republic of Hawaii. Before Hawaii became a U.S. territory, its army consisted of a royal household guard and militia units. A report and rosters of these groups are at the Hawaii State Archives along with records of the Hawaiian navy and the treason trials held after the 1895 counter-revolution.
